Many think that the existence of evil disproves God’s existence. Nothing could be further from the truth. Evil is a real problem we must wrestle with, but it argues for God’s existence, not against it.
For evil to be a problem, evil has to be real – not just an expression of human desires, preferences, or opinions. Evil is the absence of good, so for evil to be real, an objective standard of goodness must exist that transcends human beings.
What is the source for that standard? God. He is the Good, and we recognize good because we are made in His image.
Besides, denying God’s existence because evil exists does nothing to solve the problem of evil. Only if God exists can we have hope that evil will be overcome and those who commit evil face true justice for their moral crimes.
